High availability / Question about carp with 1 VIP
« on: March 17, 2023, 12:01:39 pm »
Hello,
im new to opnsense and moving our firewall from sonicwall to opnsense.
I have a question.
I have configured HA with CARP like
1 WAN Address for both Firewalls + 1 VIP
1 MGM Address for both Firewalls + 1 VIP
PFSync Interface 1 IP for Firewall1 and 1 for Firewall2
like 20 VLAN Interfaces with ONLY 1 VIP no physical IP on the interfaces
I tested a HA last week and this was working totally fine and everything got successfully transfered to the backup FW.
In the docs I read now, that you normally have to have 3 IPs with every VLAN..
In my case this is not possible because we got a lot of small vlans with not enough ips for that. Because my HA was successful whats the negative point in only having WAN and MGM with 3 IPs and all other vlans only got 1 ?
Thanks for your help
